"Dragonfly Treasure House!" , Gently spit out four words, such an obvious thing, although I haven't touched it for a long time, Xu Yun only thought about it and remembered it. [Full text reading. 】

The Flying Dragon Emperor under the command of the Sea Emperor, but he obtained it from the Dragon Fly Treasure House he encountered in the underground world, but in his impression, the Dragon Fly Treasure House was only a few meters high last time, and now this dragon is tens of meters in size, and it is not clear what it is that occupies his field of vision?

Of course, Joan of Arc had an impression of the name of the Dragon Fly Treasure House, and the Dragon Fly Treasure was attacked by her before, so she pointed to it suspiciously, and asked uncertainly about the huge deadwood-like treasure house in front of her:

"This is the Dragon Fly Treasure House where you can get a sixth-order flying dragon after you get through? How do you feel so much bigger? She had seen the size of the dragon fly treasure house with her own eyes, so of course she noticed that something was wrong.

Taking a step forward, Xu Yun touched the dead wood with his right hand, and if he wanted to know the specific situation, he just asked directly, anyway, there was a hint when he entered the treasure house, and it didn't mean that he would enter directly if he touched it.

[Do you want to enter the Dragon Fly Treasure House?] ,Yes/No,You can enter 10,000 units of creatures (this treasure house can be designated to choose nine camps of sixth-order troops or resources, each time you survive a wave of attacks, the enemy's attributes will be doubled, the more you will gain, there is no loss in the death of the treasure house, you can return to the state of entry when you exit, you can choose to quit at any time, and the reward will be settled when you exit)]

The same system prompt as a normal treasure house sounds, but it has a very different content.

Maybe it's because it's in the Golden Valley, so the rules have changed slightly, it's not like in the past, it's a fixed production of sixth-order flying dragons, but the nine camps of sixth-order troops can be selected, and if you don't like sixth-order troops, you can even choose resources.

The system prompt will only ring in the ears of the individual, so Xu Yun did not choose to enter, but directly turned around and said the content of the prompt, wanting to see the opinions of the heroes under his command.

Joan of Arc spoke first, and said with an excited expression on her face:

"My lord, this is a very good opportunity!" , If you can choose any sixth-order class of the nine camps, it means that you can choose the sixth-order cavalry, and this class will be upgraded to a seventh-order class under the strengthening of the Sun Summon, which is really a godsend, and this kind of opportunity to expand your strength on a large scale is not always encountered.

"Hmm!" Of course, Xu Yun knew this, so he was very much in favor of Joan of Arc's opinion, just to see if others had any different opinions, but found that everyone was the same as himself, and was in favor of taking the opportunity to expand the cavalry ranks.

After all, for the Reincarnation Legion, the number of high-level troops is far from enough, especially when the target is directly aimed at the nine planes, and the number of troops is not enough.

Once you understand what you should choose as a reward, the next step is to choose to carry the class, and because there is nothing to lose in death, it means that whoever you want to play.

"Int, Xana, Joan of Arc, let's go in, enter the ...... of the troops, Xiaobai commands the Aurora Warlock to search around when we enter the treasure, and Angel is responsible for the defense", to take those troops Xu Yun had a plan in his heart, so he began to roll call, and at the same time arranged the task of not entering the treasure house heroes.

"Yes!"

"Yes!"

Phew!

All the heroes acted according to Xu Yun's command.

A large number of troops dispersed, leaving only Xu Yun and a few heroes under his command, a total of 10,000 units of troops standing in place, and these troops were the entrants.

The hand touched the dead tree again, and the prompt sounded again.

Reward choice cavalry! Be!

This time, Xu Yun did not hesitate, and immediately chose the sixth-order cavalry of the castle camp as a reward, and at the same time decided to enter directly, it can only be said that the plane fragments are worthy of being a place under the rules of balance that is specially used to improve the strength of players, and there are too many good things.

Under the change of the light curtain, the 10,000 units around the Dragon Fly Treasure House disappeared in place.

The sight was dark, but Xu Yun, who had some experience in the treasure house, did not panic, he knew the rules of the treasure house, and it would not be such a thing as just opening his eyes and finding himself falling into the mouth of a monster, after all, this is a treasure house and not a random teleportation.

There was a feeling of softness on the soles of his feet, and there was a faint rancid smell pouring into his nose, and with the name of Baowu, even if no one said Xu Yun, he could understand where he was.

His gaze quickly returned to normal, and then Xu Yun saw that among the troops around him, those seventh-order Sun Knights who were on the outermost level, and the tall war horses wearing golden-red steel horses under their seats were slowly sinking downward.

Yes, at this time, Xu Yun and his troops were already on a swamp with sparse and withered grass.

The black ground under the soles of the feet looks fine, but when you walk around, it will sink like glue for a few centimeters or so, and if the weight is a little heavier, it will be like those sunknights who are sinking, and the four hooves of the war horse have sunken into the swamp or so half a meter deep.

At this time, the Sun Knight Force, although it cannot be said that it is completely inmobile, but at least the mobility is absolutely not one in ten, let alone launching a charge, even if it is a normal movement, it is not bad to be able to move more than ten meters in a minute.

And this time, Xu Yun entered the Dragon Fly Treasure House and chose to bring only four troops, namely 2400 units of the 7th-order Burning Sun Dawn Cavalry, 358 units of the Burning Sun Sacrifice, 7228 units of the 3rd-order Burning Sun Archer, and ten supply vehicles.

This configuration was carefully selected by Xu Yun, because the seventh-order Lieyang Xiao cavalry, under the leadership of Joan of Arc, could take over the front row of the dragon spearmen.

In the case of restricting the number of creatures entered, of course, it is necessary to choose the Burning Sun Cavalry, a seventh-order class with stronger individual combat effectiveness, as a meat shield.

Even if Xu Yun had already guessed in his heart before entering, the ground type was the swamp, the ground type of the Tianke cavalry, and the others, whether it was the Sun Sacrifice or the Sun Shooter, or the supply vehicle, were all chosen for the purpose of playing the maximum output, because after exiting the treasure house, he was reset to the state of entry, so he was not afraid of any losses, and he only needed to think about how to hit the maximum damage.

"Set up the formation, move fast!" , In the troops, the Sun Shooter acted as usual, and was not affected by the swamp type at all, under the command of Xia Na, the formation was quickly adjusted, and all the cavalry slowly moved into a circle, and then the Sun Shooter, the supply vehicle, the Sun Sacrifice, and the circular formation where the hero and Xu Yun were standing.

The supply vehicle can be placed between the two ranged troops, so that the supply can be completed faster, so that the long-range troops can continue to output energy.

Holy Spirit forbid!

Attack Acceleration!

Xu Yun threw out these two perverted first-order battle magics, the total number of troops was only 10,000 units, he only needed to bless them once, otherwise why would he have to bless all the troops outside before entering, but since he could bless them all at once, there was no need for that.

Buzz!!

Less than a minute after the camp was set up, the sound of scalp-tingling wings vibrating rang out from all around.

It's not that the enemy making this sound is too strong, but that the sound is similar to the sound made by creatures such as flies and bees in the real world when they fly, and even if you know that the other party is not strong, it still makes people's scalp tingle.

As far as the eye could see, in this swamp where there was no sunlight, but the light was still sufficient, a few hundred meters away, there were all the sparse trees, and the same as the fog, but with extremely lethal obstacles.

At this time, a large number of poisonous flies and dragon flies appeared in the distance on all sides, and after they appeared, they flew towards the swampy area where Xu Yun and the others were located, without any trees, only a small amount of withered grass about half a meter high.

"Attack!" , Xana's voice rang out.

These dragon flies appear directly within a range of 500 meters, so they can shoot directly without even unfurling the military flag.

If it's other types of long-range troops, you may have to wait for the opponent to enter the range before you can attack, if you want to exert maximum firepower, you must also put the opponent into the best range radius, but the Sun Shooter has a range of more than half a kilometer, and there is also the characteristics of undiminished damage within the range, which means that you can send a long-range attack a few hundred meters in advance, and the Sun Shooter is so capricious.

Shout!

The bolts dragged the blue-gold tail flames, illuminating the gloomy swamp without sunlight like beams of flame bursting.
